Abstract
The present application relates to a method and an apparatus for monitoring DCI. The method includes: receiving a DCI from a BS, wherein the DCI includes an indicator; determining one or more sensing beams used by the BS to perform a LBT procedure according to the indicator and a higher layer signaling; and determining one or more transmission beams used by the BS to transmit PDCCH according to the indicator and the higher layer signaling, wherein the one or more transmission beams are within a spatial region of a CO initiated by the BS after completing the directional LBT with the one or more sensing beams.
